Trevoh Chalobah's 53rd-minute red card proved costly for Chelsea as Brighton came from behind to secure a dramatic 3-1 victory at Stamford Bridge.
In an incident-packed game at Stamford Bridge, Chelsea had been in full control after what Sky Sports' Paul Merson described as an "outstanding" first-half display from the Blues.
Enzo Fernandez's header had given them a deserved lead midway through the opening 45 minutes but for the second successive league game, a red card changed the game for the Blues.
Early in the second half, Andrey Santos inexplicably played the ball to Diego Gomez, who looked to get straight in on goal. However, the Brighton man went down just outside the area after a tangle with Chalobah. Chelsea initially thought they might get away with one until VAR intervened.
